Dold Safety Wireless Safety Sil3 Cat 4

The TÜV certified wireless safety module UH 6900 is suitable for safety requirements up to Cat. 4 / PL e or SIL 3. The safety modules each have 3 two-channel safety inputs (such as emergency stop, light curtain, safety gate, etc.) and 1 safety output with 3 redundant contact paths. In addition, the modules each provide 8 inputs and outputs for user-specific control functions. Two additional status semi-conductor outputs, one indicator output for reception quality, and the USB interface provide for comprehensive diagnostic options.

Safe operating modes, selectable system start – simple and functional. The following operating modes can be selected using the rotary switches:

• Full safety mode
• Cross safety mode
• Safety mode with selectableoptional radio control

This allows you to quickly adapt the system to your safety application. In addition, automatic, manual, or two-hand start options are available for system start.

Operating mode 1:

Full safety mode

Safe, wireless emergency stop – safely separate system components and zones

Just two UH 6900 wireless safety modules are required to fully secure two hazardous zones. Both wireless safety modules are connected by a bidirectional safe radio connection.

If a safety function is triggered (such as emergency stop, safety gate, etc.), both UH 6900 wireless safety modules shut down the entire system in both hazardous areas in a safe controlled manner.
